[osg-users] UpdateCallback

[Robert Osfield]

Hi Julie,

You can't pass any different arguments to a NodeCallback::operator()
methods as it's the standard traversal that calls the method.

What you do get is the Node* and NodeVisitoro* pointers to the node that
it's attached to and the visitor that is traversing, you can usually use
these to determine what data is relevant.

You don't say much about what you are trying to do so it's not possible to
make any specific suggestions.  What is the vertex array assigned to?  Can
you get it from the Node*?


Robert.
